Great! Anyone has suggestion on how to make the connections via proxyservers?

this is awesome! but i need to make the connections through a proxy as well :(

ReganAnderson The PDF seems to be corrupt and does not open after downloading.  Can you re-upload the file?

_johnloi Thanks for bringing this to my attention! I've re-uploaded the PDF and the link should be working now.

Brilliant work ReganAnderson !!

IMO it's worth noting that a more "off the shelve" but less flexible approach (dynamic address spaces) has been introduced with v16 which pulls the full O365 endpoint list (not just the "optimize" category) from what I understand
https://techdocs.f5.com/en-us/bigip-16-1-0/big-ip-access-policy-manager-network-access/configuring-address-spaces/what-is-address-space.html

Which brings me to my question: What's the best practice as far as O365 tunnel exclusions go - offload all O365 hosts or just the "optimize" ones?

Couple videos on this topic:

PSilva Thanks for sharing, well presented, I fully agree, always sign your work 🙂

I understand F5 is not giving MS-product specific recommendations, which is completely valid of course.

However, pardon my stubbornness, let me rephrase the question on the otherwise wonderful address space improvement in v16:
MS' recommendation seems to be to only exclude O365 endpoints used for real-time or high-volume traffic, which are the ones categorized as "optimize" on their JSON .

So what's the rationale for F5 to exclude all hosts instead?
It's not ideal from my perspective, e.g. since login.microsoftonline.com is also hit directly by clients in that case, which means MS authentication-wise sees a non-corp IP from our VPN clients and thus considers them "off network" which has implications on conditional access.
On a more general layer, as you indicate on youtube, there's a risk to excluding hosts from the tunnel. So we'd prefer to avoid excluding more than absolutely necessary.

On our end we're planning to address this manually by pointing our APMs to an internal server where we cache the O365 endpoint list and modify the content (e.g. using jq) to take out any non-"optimize" categories.
And we'll likely do similar customizations by abusing the "zoom" template to cover some of the other applications we're excluding from VPN. Not ideal, but still WAY better than keeping exclusions up to date by hand.

Hi sh00b. Apologies for the delay. I'll need to ask PM/PD as to the rational. In the meantime, I did find a few articles about the set up for O365 but based on your response, you may have reviewed these already. 

Please shout when there's news from PM

Here's how we might work around it using python for the time being 🙂

import requests
import json

# Fetch the data from the web service
response = requests.get("https://endpoints.office.com/endpoints/worldwide?clientrequestid=b10c5ed1-bad1-445f-b386-b919946339a7")

# Parse the JSON data
data = json.loads(response.text)

# Create an empty list to hold the Optimize entries
optimize_entries = []

# Iterate over the entries in the data
for entry in data:
    # Check if the entry is categorized as "Optimize"
    if entry["category"] == "Optimize":
        # Add the entry to the list
        optimize_entries.append(entry)

# Convert the list of entries to JSON
optimize_json = json.dumps(optimize_entries)

# Print the JSON data
print(optimize_json)
